Although Shi Lei has an appraisal card to use, he can use the appraisal card to measure the true value of these raw stones and then buy them all, so that he can make money.

However, after all, the identification card is a consumption card. If you use it once and once, Shi Lei believes that he will still encounter many such situations in the future. Even though he has accumulated seven or eight opportunities to use the identification card, he still feels that this is far from enough.

It is easy to say that the black card gives the task. Every time it sets up a task, it needs to increase the chance of using the identification card three times. But now, Wei Boti has become the assistant of Beibeila, the leader of the Dark Night Eye. Shi Lei may be asked to help the Dark Night Eye to identify various things. If Shi Lei does not have the opportunity to use the identification card at that time, this will make the situation very embarrassing.

Therefore, what Shi Lei needs is his own growth, and relying entirely on this type of consumption card is not the case.

Shi Lei gradually began to understand what the black card meant to give him the reputation system.

The various learning cards he originally looked down upon may be the ultimate purpose of black cards.

After all, Shi Lei's current brain domain development is much more than that of humans on this earth. Perhaps it is incomparable to humans in the universe where Black Card used to be, but it is enough for him to bear and accommodate these various cards far beyond Earth's technology.

To put it bluntly, Heika is trying to get Shi Lei as close to the civilization of the universe where it once was.

After dark, Shi Lei and Qu Xingye returned to the hotel and after dinner, they went back to their rooms.

After Shi Lei returned to the house, he called out the reputation system.

He saw his reputation increase a little more.

Not many, but there are more than one thousand points. With the remaining reputation value in the past, his reputation value has reached more than three thousand three hundred points.

Taking out two points of reputation, Shi Lei checked the composition of more than a thousand points.

Basically, there are some scattered reputation values. The larger ones come from Li Qianhaocheng, Crawford, Jenny and Duke Scola, each of whom contributed more than 100 to dozens of points. Among them, Li Qianhaocheng contributed the highest reputation value.

Philip, the cousin of Jenny who was deeply humiliated by Li Qian Haocheng, also contributed more than twenty points of reputation.

What surprised Shi Lei was Qu Xingye and Gong Da, the boss behind this trade fair, both of whom contributed more than ten points of reputation.

The whole combination looks like almost 700, and after doubled, it reached more than 1,400.

When closing the detailed query of reputation value, Shi Lei saw Xu Zhida's name. Xu Zhida actually contributed more than fifty points of reputation value. In this list of reputation value contributions, he is second only to Li Qianhaocheng, Crawford and Jenny, and is higher than Duke Scola.

Shi Lei frowned and shook his head, "It seems that Mamba is still quite resentful this time. Is he so unwilling to be transferred to the UK?"

Didn't care much, Shi Lei returned to the main page.

There are more than 3,300 reputation values. If you want to get a skill or knowledge level of up to 1,000 knowledge, that is, a card for each elementary and middle-level high school, it happens to be 3,300. This number is really a bit of a scam.

Shi Lei entered the redemption interface and searched carefully. Sure enough, he found the card of primary jade mastery. After entering the C-level redemption, he found the corresponding jade mastery from the one thousand reputation value redemption and one thousand five hundred reputation value redemption respectively.

But what does it mean to be proficient in jade? Shi Lei is really a little unsure.

Jade is of course a jadeite, and it belongs to jadeite, but Shi Lei always thinks this division is a bit unusual.

But Shi Lei couldn't tell what was wrong.

He was not in a hurry to redeem these, but continued to look for parts related to the word "Jade" in the learning card.

Soon, he saw that he was proficient in gems again.

Shi Lei's brows were frowning even tighter. Is it proficient in gems? Jade should also belong to the gems category.

He didn't dare to neglect, so he immediately opened his mobile browser and began to query the concept of gems.

After checking, Shi Lei suddenly realized.

It turns out that gems can be divided into narrow and broad meanings.

In a broad sense, gemstone refers to the kind of dietary therapy or mineral decoration that can meet the requirements of jewelry after being pondered and polished, including diamonds, various jades, and even amber with a soft texture.

However, gemstones in a narrow sense only refer to natural mineral crystals that can be used for jewelry, including single crystals and double crystals.

Jade belongs to a fibrous aggregate, and in a narrow definition, it does not belong to the category of gems.

Even jade is divided into nephrite and jadeite. The narrow-sense jade that is more recognized internationally only includes jadeite, but does not agree with the nephrite represented by Hetian jade.

This is embarrassing, the definition is a bit unclear enough!

The jade mastery that Shi Lei just found was obviously not covered by gems.

But it's pretty good. Jade is jadeite and will be counted among jade anyway.

After such a thing, Shi Lei became more cautious and continued to search for learning cards, but he found a card that made him breathe even more.

Proficient in jade materials!

Haven’t you already mastered jade? Why is there another mastered jade?

Shi Lei's brows frowned deeply.

After online inquiry, the definition of jade that Shi Lei saw was made of natural jade. However, he failed to find the exact definition of jade materials.

The words jade materials and jadeware echoed in Shi Lei's mind, and he created the definition of jade materials by himself.

Since jade and jade materials are distinguished, and the definition of jade is processed utensils, then jade materials refer to various jades before they have been processed.

This means that what Shi Lei needs now is proficiency in jade materials, because he is facing jadeite raw stones. Of course, the raw stones are not processed objects, but can only be jade materials.

He let out a sigh of relief, Shi Lei thought to himself, fortunately, he did not hurry to exchange jade artifacts and master it, otherwise, this time the exchange would have been in vain.

After hesitating for a moment, Shi Lei decided to use his reputation. He exchanged for the primary jade mastery, medium jade mastery and high-quality jade mastery.

After using them separately, Shi Lei recalled the jadeite rough stones he saw during the day, and had an intuitive and clear understanding of these things in his mind. He could even feel that among the rough stones, valuable jadeite can be produced.

But he also understood that he was just a person who had a very deep understanding of raw stones. Perhaps no one on this earth who studied various jade rough stones could have a deeper understanding of these than him. However, this is not certain, and there will definitely be some mistakes.

However, with these three learning cards as the foundation, Shi Lei wanted to use the more than 4 million independent funds he had in his hands to buy a part of the raw stones and ensure that their value-added should be no problem.

If you want to judge these rough stones more accurately, you may still have to rely on an identification card.

In order to verify his understanding of these rough stones, this time, the identification card may still be used.

But no matter what, Shi Lei was already confident about choosing the raw stone tomorrow. He decided to rely on his current understanding of the jade material to choose first, and if it really doesn't work, then use the appraisal card.
